The Wild confirmed Thursday that Harding is undergoing treatment for the disease, which attacks the body's immune system and affects the central nervous system. The Star Tribune first reported the news.

"Our thoughts and prayers are with Josh and his family following the news that he has been diagnosed with multiple sclerosis. Josh's competitive fire has led him to a successful career in the NHL and we know he will approach this new battle in the same manner." said Wild GM Chuck Fletcher.

MS symptoms can include problems with balance, vision and fatigue.

Harding signed a three-year, $5.7 million contract this summer. He played in a career-high 34 games last season.
